This question is similar to my previous one: how to communicate with Rails in Ember but some things have changed. Now I know that a kudo is modelled in the server and has the following fields:
- value
- comment
It belongs to a user. The current implementation is as below:
<a href="#" class="btn btn-primary" {{action "addKudo" user}}>add</a>
Sks.ApplicationRoute = Ember.Route.extend
  events:
    addKudo: (user) ->
      console.log event
      self = @
      token = $('meta[name="csrf-token"]').attr 'content'
      currentUserCon = @controllerFor 'currentUser'
      kudosLeft = currentUserCon.get 'kudosLeft'
      showFlash = (type, message) ->
        $("#flash")
          .addClass(type)
          .empty()
          .append(message)
          .show()
          .fadeIn()
          .delay(2000)
          .fadeOut 'slow'
      $.post("/kudos", user_id: user.get("id"), authenticity_token: token)
      .done((data, status) =>
        if kudosLeft > 0
          currentUserCon.decrementKudos 1
          showFlash 'alert-success', 'You\'ve added a kudo!'
        else
          showFlash 'alert-error', 'There\'re no kudos left!'
      )
      .fail (data, status) ->
        showFlash 'alert-error', 'Oops! An error occured!'
But now, I'd like to make use of Ember-Data and send a POST request to /kudos (and I'd like to get rid of the jQuery ajax part). Please have a look:

Having the following model:
Sks.Kudo = DS.Model.extend
  user: DS.belongsTo 'Sks.User'
  value: DS.attr 'number'
  comment: DS.attr 'string'
how can I achieve this? What are the neccessary steps to do this? Could anyone shed some light?
The next question is: where select and text area value should point to (bindings)?
